[1-1. Outline of Information Processing System]

First, a configuration example of an information processing system 1 according to the embodiment of the present disclosure will be described. FIG. 1 is a diagram illustrating outline of the information processing system 1 according to the embodiment of the present disclosure. As illustrated in FIG. 1, the information processing system 1 includes a display control device 10, a display unit 150, and a terminal 170.

The display unit 150 has a function of displaying a screen 50 according to a control signal provided in a wireless or wired manner from the display control device 10. Types of the screen 50 displayed at the display unit 150 are not particularly limited. As illustrated in FIG. 1, a case is mainly assumed where the display unit 150 is a head mount display (HMD) to be mounted on the head of a user U. Types of the HMD are not particularly limited, and the HMD may be a transmission type HMD or a non-transmission type HMD.

The terminal 170 is a terminal used by the user U. Types of the terminal 170 are not particularly limited, and the terminal 170 may be a video camera, a smartphone or a personal digital assistants (PDA). Alternatively, the terminal 170 may be a personal computer (PC), a mobile phone, a mobile music reproduction device, a mobile image processing device, or mobile game equipment.

The display control device 10 has a function of displaying the screen 50 at the display unit 150. The screen 50 may include content C1 to C7 as illustrated in FIG. 1 or may include objects as will be described later. The number of pieces of content is not particularly limited. Further, types of content are not particularly limited, and, as illustrated in FIG. 1, the content may be an image (such as, for example, a still image and a moving image) or may be text data. Note that while the display control device 10 is configured separately from the display unit 150 in the example illustrated in FIG. 1, the display control device 10 may be integrated with the display unit 150.

In the present specification, a technique for allowing the user U to easily scroll the content to be displayed at the display unit 150 in this manner will be mainly described.

The outline of the information processing system 1 according to the embodiment of the present disclosure has been described above.

[1-2. Configuration Example of Functions of Information Processing System]

A configuration example of functions of the information processing system 1 according to the embodiment of the present disclosure will be described next. FIG. 2 is a diagram illustrating the configuration example of the functions of the information processing system 1 according to the embodiment of the present disclosure. As illustrated in FIG. 2, the display control device 10 according to the embodiment of the present disclosure includes a control unit 110, a storage unit 120, a first input unit 131 and a second input unit 132.

The control unit 110 corresponds to, for example a processor such as a central processing unit (CPU). The control unit 110 fulfills various functions of the control unit 110 by executing a program stored in the storage unit 120 or other storage media. The control unit 110 includes a first acquiring unit 111, a second acquiring unit 112 and a display control unit 113. Functions of these respective function blocks will be described later.

The storage unit 120 stores a program for operating the control unit 110 using a semiconductor memory or a storage medium such as a hard disc. Further, for example, the storage unit 120 can also store various kinds of data (such as, for example, content and objects) to be used by the program. Note that while the storage unit 120 is integrated with the display control device 10 in the example illustrated in FIG. 2, the storage unit 120 may be configured separately from the display control device 10.

As described above, the display unit 150 is connected to the display control device 10 in a wireless or wired manner. The display unit 150 includes a first detecting unit 151, and the terminal 170 includes a second detecting unit 171. The first detecting unit 151 has a function of detecting orientation of the display unit 150. The orientation of the display unit 150 detected by the first detecting unit 151 is input to the control unit 110 via the first input unit 131. Meanwhile, the second detecting unit 171 has a function of detecting orientation of the terminal 170. The orientation of the terminal 170 detected by the second detecting unit 171 is input to the control unit 110 via the second detecting unit 171.

The first detecting unit 151 detects the orientation of the display unit 150. For example, the first detecting unit 151 may include a geomagnetic sensor and measure geomagnetic data indicating orientation of geomagnetism in a coordinate system of the display unit 150 using the geomagnetic sensor. The geomagnetic data can be utilized for, for example, a direction the display unit 150 faces (orientation in a horizontal direction). Further, the first detecting unit 151 may include an acceleration sensor and measure acceleration applied to the display unit 150 using the acceleration sensor. The acceleration can be utilized for, for example, tilt of the display unit 150 (orientation in a vertical direction).

Further, the first detecting unit 151 may further include a gyro sensor and measure an angular velocity of rotation of the display unit 150 using the gyro sensor and detect the angular velocity as a change rate of the orientation of the display unit 150. The change rate of the orientation of the display unit 150 detected in this manner can be utilized for detection of the orientation of the display unit 150 at the first detecting unit 151. Note that while the first detecting unit 151 is integrated with the display unit 150 in the example illustrated in FIG. 2, the first detecting unit 151 may be configured separately from the display unit 150.

The second detecting unit 171 detects the orientation of the terminal 170. For example, the second detecting unit 171 may include a geomagnetic sensor and measure geomagnetic data indicating orientation of geomagnetism in a coordinate system of the terminal 170 using the geomagnetic sensor. The geomagnetic data can be utilized for, for example, a direction the terminal 170 faces (orientation in a horizontal direction). Further, the second detecting unit 171 may include an acceleration sensor, measure acceleration applied to the terminal 170 using the acceleration sensor and detect change of the orientation of the terminal 170 based on the acceleration. The acceleration can be utilized for, for example, tilt of the terminal 170 (orientation in a vertical direction).

Further, the second detecting unit 171 may further include a gyro sensor, measure an angular velocity of rotation of the terminal 170 using the gyro sensor and detect the angular velocity as a change rate of the orientation of the terminal 170. The change rate of the orientation of the terminal 170 detected in this manner can be utilized for detection of the orientation of the terminal 170 at the second detecting unit 171. Note that while the second detecting unit 171 is integrated with the terminal 170 in the example illustrated in FIG. 2, the second detecting unit 171 may be configured separately from the second detecting unit 171.

The configuration example of the functions of the information processing system 1 according to the embodiment of the present disclosure has been described above.

[1-3. Details of Functions of Information Processing System]

Details of functions of the information processing system 1 according to the embodiment of the present disclosure will be described next. First, a first example will be described with reference to FIG. 3 to FIG. 9. FIG. 3 is a diagram illustrating an example of a case where content is scrolled in the first example. As illustrated in FIG. 3, the user wears the display unit 150 on his head and has the terminal 170 with part of his body (for example, a hand). The display control unit 113 displays the screen 50-A1 at the display unit 150. The screen 50-A1 includes content C1 to C7.

The first acquiring unit 111 acquires the orientation u of the display unit detected by the first detecting unit 151. Further, the second acquiring unit 112 acquires the orientation t of the terminal detected by the second detecting unit 171. Here, the display control unit 113 scrolls content according to the orientation u of the display unit. By this means, it is possible to allow the user to easily scroll the content. Further, the user can scroll the content intuitively.

The orientation t of the terminal can be also used by the display control unit 113. In such a case, for example, the display control unit 113 may perform predetermined control according to the orientation t of the terminal. By this means, because it becomes possible to also use the orientation t of the terminal, for example, even if it is difficult to adjust the orientation u of the display unit, it is possible to perform input by utilizing the orientation t of the terminal. Possible examples of the case where it is difficult to adjust the orientation u of the display unit include a case where it is difficult for the user to maintain the orientation of his head to fixed orientation for a long period of time. For example, the display control unit 113 may scroll the content according to a relationship between the orientation u of the display unit and the orientation t of the terminal.

While the relationship between the orientation u of the display unit and the orientation t of the terminal may be any relationship, as one example, the display control unit 113 may scroll the content according to the orientation t of the terminal which is relative to the orientation u of the display unit. More specifically, the display control unit 113 may scroll the content in opposite orientation to the orientation t of the terminal which is relative to the orientation u of the display unit. FIG. 3 illustrates a case where the orientation t of the terminal which is relative to the orientation u of the display unit is leftward when viewed from the user. At this time, the display control unit 113 may scroll the content to the right, which is opposite to the left, in order for the user to easily view a left side of the screen 50-A1.

Scroll speed of the content is not particularly limited, and, for example, the display control unit 113 may control the scroll speed of the content according to an angular difference between the orientation u of the display unit and the orientation t of the terminal. More specifically, the display control unit 113 may increase the scroll speed of the content for a larger angular difference between the orientation u of the display unit and the orientation t of the terminal. This control allows the user to adjust the scroll speed of the content intuitively.

Note that while a case has been described in the above description where the orientation t of the terminal acquired by the second acquiring unit 112 is used by the display control unit 113, it is also possible to use some kind of reference orientation in place of the orientation t of the terminal. For example, the display control unit 113 may scroll the content according to the orientation u of the display unit which is relative to the reference orientation. More specifically, the display control unit 113 may scroll the content in opposite orientation to the orientation u of the display unit which is relative to the reference orientation. The reference orientation may be set in advance by the user or may be set by the control unit 110.

Here, the display control unit 113 only has to stop scrolling of the content when the orientation u of the display unit matches the orientation t of the terminal or the orientation falls within a predetermined range. FIG. 4 is a diagram illustrating an example of a case where scrolling is stopped in the first example. Referring to FIG. 4, because the orientation u of the display unit matches the orientation t of the terminal after the content is scrolled, a screen 50-A2 including content C4 to C10 is displayed by the display control unit 113 and scrolling of the content is stopped in a state where the screen 50-A2 is displayed.

Further, while focus is placed on content C7 in the center among content C4 to C10 in the example illustrated in FIG. 4, content on which focus is placed is not particularly limited. In this state, for example, when the user performs predetermined operation to the terminal 170, the display control unit 113 may select content on which focus is placed. While the predetermined operation is not particularly limited, the predetermined operation may include operation of the user tapping the terminal 170.

FIG. 5 is a diagram illustrating an example of operation for selecting the content C7 in the first example. Referring to FIG. 5, when the user taps the terminal 170 in a state where focus is placed on the content C7, the display control unit 113 selects the content C7 on which focus is placed. The display control unit 113 perform any control on the content C7 after the content C7 is selected. For example, as a result of the content C7 being selected, a selection result screen including enlarged content C7 may be displayed.

FIG. 6 is a diagram illustrating an example of a case where a selection result screen 50-A3 is displayed as a result of the content C7 being selected in the first example. Referring to FIG. 6, the display control unit 113 displays the selection result screen 50-A3 including the enlarged content C7 at the display unit 150. Further, for example, when the user performs predetermined operation on the terminal 170 in a state where the selection result screen 50-A3 is displayed, the display control unit 113 may be able to return the screen to the previous screen. While the predetermined operation is not particularly limited, the predetermined operation may include operation of the user holding down a button on the terminal 170 for a long period of time.

FIG. 7 is a diagram illustrating an example of operation for returning display from the selection result screen 50-A3 to the previous screen 50-A2 in the first example. Further, FIG. 8 is a diagram illustrating an example of a case where display is returned from the selection result screen 50-A3 to the previous screen 50-A2 in the first example. Referring to FIG. 7 and FIG. 8, when the user holds down a button on the terminal 170 for a long period of time in a state where the enlarged content C7 is displayed, the display control unit 113 displays the previous screen 50-A2 at the display unit 150.

FIG. 9 is a flowchart illustrating flow of operation of the display control device 10 in the first example.

Note that the example illustrated in FIG. 9 is merely one example of the flow of the operation of the display control device 10 in the first example. Therefore, the flow of the operation of the display control device 10 in the first example is not limited to the example illustrated in FIG. 9.

As illustrated in FIG. 9, when the orientation u of the display unit is detected by the first detecting unit 151, the orientation u of the display unit is input to the control unit 110 via the first input unit 131, and the orientation u of the display unit is acquired by the first acquiring unit 111 (S11). Subsequently, when the orientation t of the terminal is detected by the second detecting unit 171, the orientation t of the terminal is input to the control unit 110 via the second input unit 132, and the orientation u of the display unit is acquired by the second acquiring unit 112 (S12).

The display control unit 113 scrolls the content according to the orientation t of the terminal which is relative to the orientation u of the display unit (S13). Note that after the operation of S13 is finished, the control unit 110 may return to the operation of S11 again or may finish the operation. The first example has been described above.

A second example will be described next with reference to FIG. 10 to FIG. 14. FIG. 10 is a diagram illustrating an example of a case where focus is moved in the second example. As illustrated in FIG. 10, the user wears the display unit 150 on his head and has the terminal 170 with part of his body (for example, a hand). The display control unit 113 displays a screen 50-B1 at the display unit 150. The screen 50-B1 includes objects B1 to B4.

The first acquiring unit 111 acquires the orientation u of the display unit detected by the first detecting unit 151. Further, the second acquiring unit 112 acquires the orientation t of the terminal detected by the second detecting unit 171. Here, the display control unit 113 moves focus according to the orientation t of the terminal. By this means, the user can easily move the focus.

The orientation u of the display unit can be also used by the display control unit 113. In such a case, for example, the display control unit 113 may perform predetermined control according to the orientation u of the display unit. By this means, because it becomes possible to also use the orientation t of the terminal, variations of the operation which can be input by the user can be increased. For example, the display control unit 113 may move the focus according to a relationship between the orientation u of the display unit and the orientation t of the terminal.

While the relationship between the orientation u of the display unit and the orientation t of the terminal may be any relationship, as one example, the display control unit 113 may move the focus according to the orientation t of the terminal which is relative to the orientation u of the display unit. More specifically, the display control unit 113 may move the focus according to the orientation t of the terminal which is relative to the orientation u of the display unit. FIG. 10 illustrates a case where the orientation t of the terminal which is relative to the orientation u of the display unit is leftward when viewed from the user. At this time, the display control unit 113 may move the focus to a position of an object B1 in an upper left region of the screen 50-B1.

Note that while a case has been described above where the orientation u of the display unit acquired by the first acquiring unit 111 is used by the display control unit 113, it is also possible to use some kind of reference orientation in place of the orientation u of the display unit. For example, the display control unit 113 may move the focus according to the orientation t of the terminal which is relative to the reference orientation. More specifically, the display control unit 113 may move the focus according to the orientation t of the terminal which is relative to the reference orientation. The reference orientation may be set in advance by the user or may be set by the control unit 110.

When, for example, the user performs predetermined operation on the terminal 170 in a state where focus is placed on the position of the object B1, the display control unit 113 may be able to select the object on which focus is placed. The predetermined operation is not particularly limited, and may include operation of the user tapping the terminal 170.

FIG. 11 is a diagram illustrating an example of a case where the object B1 is selected in a second example. Referring to FIG. 11, when the user taps the terminal 170 in a state where focus is placed on the object B1, the display control unit 113 selects the object B1 on which focus is placed. After the object B1 is selected, the display control unit 113 may perform any control on the object B1. For example, as a result of the object B1 being selected, a selection result screen including content corresponding to the object B1 may be displayed.

FIG. 12 is a diagram illustrating an example of a case where a selection result screen 50-B2 is displayed as a result of the object B1 being selected in the second example. Referring to FIG. 12, the display control unit 113 displays the selection result screen 50-B2 including content C11 corresponding to the object B1 at the display unit 150. Further, when, for example, the user performs predetermined operation on the terminal 170 in a state where the selection result screen 50-B2 is displayed, the display control unit 113 may be able to return the screen to the previous screen. The predetermined operation is not particularly limited, and may include operation of the user holding down a button on the terminal 170 for a long period of time.

FIG. 13 is a diagram illustrating an example of a case where display is returned from the selection result screen 50-B2 to the previous screen 50-B1 in the second example. Referring to FIG. 12 and FIG. 13, when the user holds down a button for a long period of time on the terminal 170 in a state where the content C11 corresponding to the object B1 is displayed, the display control unit 113 displays the previous screen 50-B1.

FIG. 14 is a flowchart illustrating flow of operation of the display control device 10 in the second example. Note that the example illustrated in FIG. 14 is merely an example of flow of the operation of the display control device 10 in the second example. Therefore, the flow of the operation of the display control device 10 in the second example is not limited to the example illustrated in FIG. 14.

As illustrated in FIG. 14, when the orientation u of the display unit is detected by the first detecting unit 151, the orientation u of the display unit is input to the control unit 110 via the first input unit 131, and the orientation u of the display unit is acquired by the first acquiring unit 111 (S21). Subsequently, when the orientation t of the terminal is detected by the second detecting unit 171, the orientation t of the terminal is input to the control unit 110 via the second input unit 132, and the orientation u of the display unit is acquired by the second acquiring unit 112 (S22).

The display control unit 113 selects an object according to the orientation t of the terminal which is relative to the orientation u of the display unit (S23). Note that after the operation of S23 is finished, the control unit 110 may return to the operation of S21 again or may finish the operation. The second example has been described above.

Subsequently, referring to FIG. 15 and FIG. 16, a third example will be described. FIG. 15 is a diagram illustrating an example of a case where focus is moved in the third example. As illustrated in FIG. 15, the user wears the display unit 150 on his head and has the terminal 160 with part of his body (for example, a hand). The display control unit 113 displays the screen 50-C1 at the display unit 150. The screen 50-C1 includes content C1 to C7 and objects B1 to B4.

The first acquiring unit 111 acquires the orientation u of the display unit detected by the first detecting unit 151. Further, the second acquiring unit 112 acquires the orientation t of the terminal detected by the second detecting unit 171. Here, the display control unit 113 scrolls content according to the orientation u of the display unit. Further, the display control unit 113 selects an object according to the orientation t of the terminal. By this means, it becomes possible to easily scroll content and easily select an object.

For example, the display control unit 113 may scroll the content according to the orientation u of the display unit which is relative to reference orientation. More specifically, the display control unit 113 may scroll the content in opposite orientation to the orientation u of the display unit which is relative to the reference orientation. The reference orientation may be set in advance by the user or may be set by the control unit 110.

In a similar manner, for example, the display control unit 113 may select an object according to the orientation t of the terminal which is relative to reference orientation. More specifically, the display control unit 113 may select an object according to the orientation t which is relative to the reference orientation. The reference orientation may be set in advance by the user or may be set by the control unit 110.

FIG. 16 is a flowchart illustrating flow of operation of the display control device 10 in the third example. Note that the example illustrated in FIG. 16 is merely an example of the flow of the operation of the display control device 10 in the third example. Therefore, the flow of the operation of the display control device 10 in the third example is not limited to the example illustrated in FIG. 16.

As illustrated in FIG. 16, when the orientation u of the display unit is detected by the first detecting unit 151, the orientation u of the display unit is input to the control unit 110 via the first input unit 131, and the orientation u of the display unit is acquired by the first acquiring unit 111 (S31). Subsequently, when the orientation t of the terminal is detected by the second detecting unit 171, the orientation t of the terminal is input to the control unit 110 via the second input unit 132, and the orientation u of the display unit is acquired by the second acquiring unit 112 (S32).

The display control unit 113 scrolls content according to the orientation u of the display unit (S33). Further, the display control unit 113 selects an object according to the orientation t of the terminal (S34). Note that after the operation of S34 is finished, the control unit 110 may return to the operation of S31 again or may finish the operation. The third example has been described above.

In the first example and the third example, a case has been described where the display control unit 113 scrolls the content according to the orientation u of the display unit. However, it is assumed that the user tries to change the orientation of the display unit 150 for the purpose other than the purpose of scrolling the content. Therefore, the display control unit 113 may determine whether or not to scroll the content based on whether or not the user inputs predetermined operation. While a case will been described in the following description where the predetermined operation is touch operation, the predetermined operation may be any operation.

FIG. 17 is a diagram illustrating a modification of the first example and the third example. As illustrated in FIG. 17, the user wears the display unit 150 on his head and has the terminal 170 with part of his body (for example, a hand). The display control unit 113 displays a screen 50-D1 at the display unit 150. The screen 50-D1 includes content C1 to C7.

The first acquiring unit 111 acquires the orientation u of the display unit detected by the first detecting unit 151. Further, the second acquiring unit 112 acquires the orientation t of the terminal detected by the second detecting unit 171. Here, as illustrated in the screen 50-D1, the display control unit 113 may determine not to scroll the content while the user does not input touch operation. Meanwhile, as illustrated in a screen 50-D2, the display control unit 113 may determine to scroll the content while the user inputs touch operation.

Note that the operation performed while the user does not input touch operation may be replaced with the operation performed while the user inputs touch operation. That is, the display control unit 113 may determine not to scroll the content while the user inputs touch operation, while the display control unit 113 may determine to scroll the content while the user does not input touch operation.

Further, in the second example and the third example, an example has been described where the display control unit 113 selects an object according to the orientation t of the terminal. However, it is assumed that the user tries to change the orientation of the terminal 170 for the purpose other than purpose of selecting an object. Therefore, the display control unit 113 may determine whether or not to select an object based on whether or not the user inputs predetermined operation.
